Application filed March 18, 1921. Serial NO. 452,833.

T 0 all whom it may concern Be it known that I, iar H. WI soN, a citizen of the United States, and a resident of New Holland, in the county of Logan and State of lllinois, have invented a new and useful Improvement in Flows, which the following is a full, clear, and exact description.

, My invention relates to improvements in plows, and it consists in the combinations, constructions and arrangements herein scribed and claimed.

An object of my invention is to provide a. novel form of plow having means for preventing the accumulation of adhesive soil on the moldboard thereof.

A further object of my invention is to provide in a device of the type described a moldboard having a fixed frame and a movable body portion.

A. further object of my invention is to provide a device of the type described that is relatively simple in construction and operation, not likely to get out of. order easily, and thoroughly practical commercially.

A further object of my invention is to provide a device of the type described in which the movable portion of the moldboard may be replaced cheaply and readily when worn out in service.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Fig. 1 is a perspective view of the device,

Fig. 2 is a plan view of the same,

Fig. 3 is a rear view of the device,

Fig. 4 is a section through the moldboard of the device, and,

Fig. 5 is an enlarged detail view of a fragmentary portion of the moldboard.

In the usual form of plow, the share, moldboard, and landside portions thereof are relatively immovable. Certain kinds of soil are very adhesive, particularly when wet,

and stick to the moldboard so that the progress of the plow through the soil is impeded and increased power is required to draw the plow. Furthermore, the soil cannot be tilled properly when the adhesive soil has accumulated 0n the moldboard and a given amount of work can be accomplished in any manner only with great difhculty and with a loss in time and labor, this being particularly true when the ordinary walking plow drawn by draft animals. is used. When my improved device is used, soil of any nature will be turned up uniformly and evenly so that the land is properly tilled.

1n carrying out my invention, 1 provide a share 1 that is made of any suitable material, such as steel or chilled cast iron, and is curved in the conventional manner. The share 1 has tne usual cutting edges and is joined to the usual landside 2 that is bolted or otherwise rigidly secured at 3 to plate a secured at 5 to a beanrG. The parts described so far are ordinary in construction and form no part of my invention except in so far they cooperate with the parts about to be described.

1 now provide a pair of curved moldboard frame members 7 and 8 having the form best seen in Figures 1 and l and. being made of any suitable material, preferably metal. The frame aen ber '2' is rigidly secured, as at S), at it lower end to the upper edge portion of the share 1 adjacent to the rear end thereof. The name member 8 is rigidly secured,

. at l0. to the upper edge portion of the share 1 ad z-nent to the forward or cutting of the latter, as shown in Fig. 1, and

,0 .ie beam 6 by means of a connector 11 so that the frame members 7 and 8 are paraliel with one another. A transversely extending roller 12 has co-axially alined studs or stub shafts 13 projecting from its ends and journalled in the frame members 7 and 8 adjacent to the lower ends of the latter so that the roller 12 will turn freely. A similar roller ll is provided with projecting studs or shafts 15 journalled in slots 16 in the frame members 7 and 8 adjacent to the upper ends thereof. The roller 1 1 is parallel with the roller 12 and can be adjusted in position relative thereto by operating adjusting screws 17 that are disposed in threaded openings 18 in the upper end walls of the frame members 7 and 8 and have their ends engaging with the studs or shafts 15.

An endless belt or apron 19 that is formed of any suitable material, such as canvass or a like strong-flexible material, is passed around the rollers 12 and 1d and is guided in its movement by a plurality of transversely extending spaced apart slats 20 which are secured to the inner side of the apron 19 and have their ends projecting bei the under sides of the frame members 7 yond the corresponding ends of the apron for slidable movement along guide grooves 21-21 in the adjacent side walls of the frame members 7 and 8adjacent their upper sides and along guide shoulders 2222 defined by longitudinal recesses 23-23 in and 8.

From the foregolng description of the va-- "rious parts of the device, the operation theredevice can be drawn more easily than an ordinary plow in performing a given WOl'I.

Obviously, the movement of the apron 19 will prevent the accumulation of soil on the moldboard as occurs when an ordinary plow is used and so detrimentally affects the operation of the latter. 7

I preferably provide a transverse brace 24 secured at 25 to the frame member 7 and at 26 to the landside so that the device em bodying my invention is sufficiently rigid for use under ordinary service conditions.

When. the apron 19 becomes worn, it may be readily replaced.

()bviously, ,many adaptations and modifications of the form of the device other than that illustrated in the accompanying drawings may be provided without'departing from the spirit and scope of my invention as disclosed in the foregoing specification and outlined more particularly in the ap pended claim, and I thereforeconsider such modifications and adaptations as my own.

I claim:

In a plow, a pair of parallel moldboard frame members," each having a rigid connection at itslower end with the upper edge portion of the plow share, said frame members being fashioned with. parallel longitudinally extending guide grooves in their inner faces adjacent to the upper edge thereof and with longitudinally extending guide shoulders oflset outwardly, from their 'in-.

ner faces along the lower edges thereof, a pair of transversely disposed parallel rollers rotatably supported between the frame members adjacent to the upper and lower 1 ends thereof, an endlessapron passed around said rollers, and spaced transverse slats secured to the inner side of said apron and ar ranged with their opposite ends in position to slidably engage the said guidegrooves and in sliding contact with said guide shoulders.
